Abstract

A project is described to determine damage to chiropteran (bat) hearing by shock waves such as those emitted by weapons and explosions. Experimental and analytical means will be used to accurately define the stimulus, particularly as regards wave form and spectra in the frequency range 10–100 kHz in which bat hearing is sensitive. Initial results regarding the stimulus as well as hearing thresholds determined via the auditory brainstem response are presented.
